Observations regarding morphology and habitat of Gaultheria procumbens L. and Gaultheria hispidula (L.)Muhl.
No full textThis paper outlines some observations regarding two members of the Ericaceae family, Gaultheria procumbens L. and Gaultheria hispidula (L.) Muhl. In this paper I compare structure and habitat of these two species based on my laboratory and field observations taken inthe summer of 1992, while I was attending classes at UMBS.http://deepblue.lib.umich.edu/bitstream/2027.42/54363/1/2799.pdfDescription of 2799.pdf : Access restricted to on-site users at the U-M Biological Station
The influence of soil pH on the growth of Wisconsin Fast Plants
No full textSoil pH influences optimal conditions for nutrient uptake and plant growth. We measured plant growth parameters including germination, height, biomass, photosynthetic efficiency, and flowering of Brassica rapa. Neutral pH was the best condition for growth followed by high pH and low pH.Biological SciencesHellquist, C. Eri
Does the addition of tobacco have allelopathic effects on the growth of Wisconsin Fast Plants (Brassica rapa)?
No full textAllelopathy is when one plant releases chemicals that inhibit the growth of another species. Following application of tobacco solutions, we measured several plant growth parameters including germination, height, biomass, and flowering of Brassica. Preliminary observations indicate that there may be an allelopathic effect on Brassica at 50% tobacco concentration.Biological SciencesHellquist, C. Eri
Assessing Gammarus sp. Survival in Different Salinity Treatments of Pond Water at Rice Creek Field Station
No full textThe salinization of the Great Lakes due to human activities has had a profound impact on native aquatic organisms. The survival of scud (Gammarus sp.) was measured in three levels of salinity, with Gammarus having a much lower survival rate in higher salinities.Biological SciencesHellquist, C. Eri
Impact of Exposure to Rock Salt on Brassica Seed Germination and Growth
No full textHigh salt concentrations in water and soils can negatively affect plant growth and health. We measured several growth parameters in the mustard Brassica rapa, including germination, height, biomass, flowering, and leaf development. Preliminary results revealed growth inhibition apparently related to the salt concentration applied.Biological SciencesHellquist, C. Eri
Evaluating the Effect of Sucrose and Fructose on the Growth Rate of Brassica Rapa in Two Soil Conditions
No full textSoluble sugar aids in the physiological growth of plants and metabolism. To understand this, the effects of the exogenous addition of sucrose and fructose to Rosette-dwarf flowers were studied according to parameters of plant size, germination, and photosynthetic efficiency. Results showed an adverse reaction to the addition of the sugars.Biological SciencesHellquist, C. Eri
The Effects of Simulated Herbivory on the Growth of a Common Greenhouse Weed
No full textHerbivory plays an important role in the growth and reproduction of plants. We studied the impacts of herbivory on Pseuderanthemum variabile by measuring height, biomass, and photosynthesis. Preliminary observations indicate that increased levels of simulated herbivory were detrimental to the photosynthetic efficiency and overall health of the plants.Biological SciencesHellquist, C. Eri
Do genotypes influence the growth of Wisconsin Fast Plants when faced with competition?
No full textCompetition between plants leads to limited resources, which may force a survival of the fittest situation. Wisconsin Fast Plants, Brassica rapa, have multiple different genotypes that influence how they grow. We measured various growth parameters, such as daily height, in two genotypes related to energy acquisition - Polycot and Yellow-Green - to determine if the genotype influenced the response to competition. Our results indicated that the Polycot genotype is a better competitor than the Yellow-Green genotype.Biological SciencesHellquist, C. Eri
How do Soil Salt Solutions Affect the Growth of Wisconsin Fast Plants
No full textExcess salt in soils can hinder plant growth by interfering with water uptake leading to nutrient imbalances and plant death. We measured several parameters such as height, leaf size, and biomass of the mustard, Brassica rapa. Preliminary results did not reveal a consistent growth response across treatments. After collecting the data, we observed that salt negatively impacted the growth in both the 2 ppt and 15 ppt treatments. However, the 10 ppt treatment was an outlier, showing no apparent negative effects on growth despite the salt being applied.​Biological SciencesC.Eric, Hellquis
